How to Grow and Care for Queen Elizabeth Rose

Queen Elizabeth rose (Rosa ‘Queen Elizabeth’) was the first Grandiflora rose, which is a cross between a hybrid tea rose and a floribunda rose. It was bred in 1954 by the American rose breeder Walter Lammerts to commemorate the ascension of Queen Elizabeth II to the throne in 1952. Grandiflora roses combine the long, tall, upright stems of hybrid tea roses with the multiple flower clusters of Floribunda roses. Queen Elizabeth rose has pink flowers and dark green, glossy, almost leathery foliage. It flowers repeatedly throughout the summer and early fall.

Roses have a reputation for requiring a lot of care and being finicky to grow. Not this one—Queen Elizabeth rose is fairly easy to grow, hardy, and disease-resistant, which makes it a popular choice, especially for rose novices. But because it is a shrub-like plant that reaches 6 feet or more in height, it requires space and is best planted towards the back of a flower bed, or as a screen.

Queen Elizabeth rose should be planted in the early to mid-fall so that the roots have time to grow and get established before the plant enters dormancy.

Queen Elizabeth Rose Care

Here are the main care requirements for growing Queen Elizabeth rose:

• Plant in full sun and rich, well-worked, moist soil that is well-draining.
• Prevent the spread of diseases by ensuring good air circulation and at least 3 feet between plants.
• Regularly prune Queen Elizabeth rose to help wet foliage from morning dew and after a rain to dry fast.
• Fertilize in the early spring and at first bloom.

Light

Queen Elizabeth rose needs at least six, better eight hours of full, direct sunlight per day.

Soil

Loamy soil is ideal. The soil should be rich, well-draining, and loose. Roses prefer slightly acidic soil with a pH between 6 and 7.

Water

The soil should be consistently moist but not wet. Poor drainage, or too much water, leads to fungal diseases.

In the absence of rain, check the soil moisture and if the top 2 to 3 inches feel dry, water the rose deeply. The roots of roses are up to 3 feet in the ground and the water needs to reach them.

Mulching around the base of your rose, ideally with wood chips or bark mulch, helps retain the soil moisture and suppresses weeds that will compete with the plant for water.

Temperature and Humidity

Queen Elizabeth rose can tolerate winters up to USDA zone 5 and hot summers up to zone 9. High humidity can be problematic, especially if there isn’t sufficient air circulation, as fungal diseases spread in humid weather, or the branches are too dense due to lack of pruning.

Fertilizer

In the early spring, as new growth starts to appear, fertilize the rose with an all-purpose fertilizer or a special rose and flower fertilizer. Fertilize again after the first bloom. A third feeding at the end of the season is only advisable in a warmer climate with a long, mild fall because new growth late in the season is vulnerable to frost.

Types of Queen Elizabeth Rose

Besides the shrub, there is a climbing variety of Queen Elizabeth with the same dark green, robust leaves, and light pink flowers. It grows on trellises, fences, and pergolas.

Pruning

Queen Elizabeth rose is deciduousand loses all its leaves in autumn, then it regrows new foliage in the spring. Deadhead the spent flowers to encourage repeated blooming.

In the late winter or early spring, before buds start to form, remove all dead and diseased wood and stems and any crossing stems. Then do a hard pruning and cut back up to one-third of the plant, which encourages growth and blooming Make sure that you sanitize your pruners with a mixture of two cups ofbleach and one gallon of water, so you don’t potentially spread any plant diseases around. Remove all the debris and dispose of it in the trash.

Propagating Queen Elizabeth Rose

As a hybrid, Queen Elizabeth rose should not be propagated from seeds because the new plant won’t be true to the parent. But you can propagate the rose from stem cuttings:

1. Using sharp pruners, take a 12-inch cutting from a stem that has recently bloomed and remove any flowers or flower buds.
2. Remove all but the top twosets of leaves on the stem.
3. Split the bottom ¼ inch of the stem into quarters and dip it in rooting hormone.
4. Fill a 6-inch pot with potting mix for roses. Poke a hole in the potting mix and insert the stem split-side down. Gently tap down the soil around the stem
5. Water it well.
6. Cover the pot including the cutting with a clear plastic bag to help retain soil moisture.Place it in a warm location with bright light and keep the soil evenly moist until you see new growth, at which point you should remove the plastic bag.

Potting and Repotting Queen Elizabeth Rose

Because Queen Elizabeth rose is a sizeable shrub, it is best planted in a garden bed, but you can also grow it in a large container. Make sure the container is one-third wider than the plant and accommodates its entire root system, and that it has large drainage holes. Adding a layer of gravel at the bottom improves the drainages and also adds weight to a plastic container so it is less prone to toppling over. Place the container in a sunny location but away from strong winds.

Keep in mind that when growing Queen Elizabeth rose as a container plant, it needs additional care in the summer (more frequent watering) as well as in the winter (insulation of the container against cold).

Overwintering

Queen Elizabeth rose is hardy and does not need any winter protection when planted in garden soil, but it benefits from a thick layer of mulch around the base to insulate the roots from the cold.

Growing the rose as a container plant is a different matter. In a container, the roots are exposed to the cold and need to be protected. There are different ways to winterize the container—you can bury it in the ground, move it to a sheltered location, or place it inside an insulating silo.

Common Pests & Plant Diseases

The most common pest attacking Queen Elizabeth rose is aphids.

Queen Elizabeth rose is described as disease-resistant, which primarily refers to its moderate resistance to black spot and powdery mildew. It can still get other common rose diseases such as stem canker and dieback, rust, botrytis blight, rose rosette disease, rose mosaic, and crown gall. Your best line of defense is to make sure the plant is healthy and keep an eye on the plant so you catch any symptoms early. A plant that has suffered winter injury or has been damaged by pruning is especially vulnerable, as lesions are points of entry for various fungal diseases.

How to Get Queen Elizabeth Rose to Bloom

One common reason why Queen Elizabeth rose does not bloom is that it does not get enough direct sunlight. If that’s the case, check the plants around it to see if you can prune them back to give the rose additional light.

Bloom Months

Queen Elizabeth Rose typically blooms in mid-summer to early fall.

What Does Queen Elizabeth Rose's Flowers Look and Smell Like?

The rose has light pink flowers and dark green leaves. It is on the light end of the fragrance spectrum and has a mild fragrance.

How to Encourage More Blooms

To encourage more flowers, make sure your roses have good air circulation and plenty of space from other plants. You also might want to check the fertilizer, as too much nitrogen in the soil can cause the plant to grow more foliage than flowers.

Common Problems With Queen Elizabeth Rose

Living up to its reputation of being a robust rose variety, Queen Elizabeth rose does not have common problems. If the buds, leaves, and flowers of the shrub get decimated in mid-summer, the culprits are often Japanese beetles and instead of spot-treating them, you might want to have a more comprehensive plan in place to control them. The same applies to spotted lanternflies, also a highly destructive pest that is attracted by rose bushes.
